IMPROVEMENT BUSH-NOZZLBS.

v'ro v.tLL wHoM IT MAY ooNcnnN:

Be iti known that I, JOHN B.'1\IIC11ELL, of Portland, in the county of C umbcrland, and Stat-c of Maine, have invented .a new und useful Improved Hose-Nozzle; and): hereby declare the following to be a. full, clear, and exact description thereof, which will enable othersto make and use my invention, reference being Ahud to theaccompnnyingdrawings, Aforming part-ot" this specication, in which I Figure 1 shows a. side view when in'use.

-Figure '6, ascctionof nozzle. vDuring the progress of fires it is often convenientyund sometimes necessary, thut'ithe--mugnitude of the stream of water thrown should be increased, to give greater volume ut. close quarters, or diminished, that it may be projected to a. greater heightor distance, or the nozzle changed so as to permit the stream lto 'be scattered like spray, to he used in case of' dense smoke concealing the flame from thel view. vAis'the common n'oz.v zlesare now made, it isnocessury to cut off the-stream, or stop, the engine, while they are being thus changed,

'which causes-much delay end-hindrance. I am aware ot' Acertain inventions made to meet this inconvenience,

und do not claim the same, they being dissimilar to mine.

My invention relates both to the method of coupling and uncoupling theA nozzles, and-to the construction of' the nozzles themselves.

j In the drawings, 'B is a tube, connecting at a with the hose of an engine. A is a. vibratuble or swinging 'cap or ring, havngarms la pvoted or jointed at c, so that the ring A can be turned oil` 'from the tube B, as

indicated in lig.. 2. Y

4The ringlras `one oi` these nrms b on each ofdtwo opposite sides. d isn metallic belt attached to ther-ing. The purpose 'of 'this will bc hereafter explained. 11 are trusses to strengthen the narrowest or thinnest portion of the ring A.v C is a nozzle, through which vthe water is ejected, as indicated in thesection, igffi.A It has a, rim or shoulder, e,'and studs a little above the' rim, (seef.) Fig. 5 shows the ring A with a. shoulder, y, and: slots h.` The nozzle C is united to the ring Aus follows: I

Turn oi the ring, es in fig. 2, pass vthe-nozzle up through -the ringA until'the studsfpass through slots hnthen give the' nozzle' a partial turn, und it will. be held on the ring by the studsf above the Shoulder g o? thering, and the nozzle-shoulder e below the shoulder g. 4 Then slip the ring over theheadof tube B, ns seen in {ig..1. z' is n. ring, with an `interior screw-thread, and turning on the screwj o n the tube B. The arms are zpivotcdto tliisairg 2'. -When the ringiA and nozzle C have been placed over the .tube B, es in fig. 1, the tube BIisthen-screweil upwardly, or ring z' downwardly, which operation presses the top of the tube B firmly against the bottom o the nozzleC, for instance, thus rendering the jointtight. A shoulder, L', gasket m, and projection n, further perfect thcjoint. Y y A Y 'It'p'will bc observed that the ringA crm only be thrown off in the direction of the side on which the belt'a? -'is placed, (sce fig. 2,) thc belt preventing the opposite movement.. -Thus the belt d being on the upper side of thettube 13,515 the 'pipe-manor other'operator holds it, or turned toward him, it `prevents water from flying into 'hisface when the ring is moved oil' or on the tube B. C is the nozzle. The Vaperture o can be varied in diierentnozzles 'to suit the requirements ofthe euse in which the same A may be used, .it being only necessary that all thenozzles'should conform in size nt the bottom to the ring A', so us to t therein.

When' a nozzle is to be removed, screw downwardlyvthe tube B, throw back ring A, as Ain iig. 2,l turn the nozzle C sovthatv4 the studsfwill slip through vslots h, und the .nozzle will drop down throughvring A, and another can beqinserted, as before described. I

Thus it will bo seen, pipes or nozzles can be changed witli great celerity, without stopping the play of the engine, and with but little trouble, and no danger to the firemen.

D is the spreader, attachable to the ring A in the same manner as the nozzles C, but having the apertures 1 2 .3, as illustrated in lig. 4, andflarng inwardly to give great force, (see seetion, iig. 3.)

It will be seen from the small size of the nozzles C, that a large number can, witlrlittle eomparative expense, be supplied toeach engine.

What I claim as my invention, and desire to`secure by Letters Patent, is-

1. A hose-nozzle, having the adjustable tube B, ring A, arms b, and ring z', arranged to operate as and for the purposes described. .l

2. In combination with the above, the beit d, as and for the purposes set forth.

JOHN B. MITCHELL.
